You can ABSOLUTLY use 2 payment methods. People do it all the time if tkt is more then what they can put on one credit card. Also, ticket counters ALL take cash. The only restriction is they must break the fare the way the tkt says when using 2 forms of payment. You can't just pay 1000 in cash. Let's say tkt costs $2167. When they look at the fare, let's say its 800 each way + 567 in taxes. You can pay 800 + 1367. OR 1600 + 567. Make sense?
